实施例1Example 1
请参照图1，本发明的轴向恒力浮动装置的优选实施例，其包括有浮动轴1、恒压外缸体2、恒压内缸体3和浮动活塞4：Referring to Figure 1, a preferred embodiment of the axial constant force floating device of the present invention includes a floating shaft 1, a constant pressure outer cylinder 2, a constant pressure inner cylinder 3 and a floating piston 4:
恒压内缸体3和浮动活塞4分别套设于浮动轴1的外部，恒压外缸体2套设于恒压内缸体3和浮动活塞4的外部，恒压外缸体2和恒压内缸体3之间形成一腔室，浮动活塞4一端与浮动轴1固定连接，另一端位于腔室内并将腔室分隔为第一腔室5和第二腔室6，恒压外缸体2的侧壁上设置有第一进气口7和第二进气口8，第一进气口7与第一腔室5相连通，第二进气口8与第二腔室6相连通。The constant pressure inner cylinder 3 and the floating piston 4 are respectively sleeved outside the floating shaft 1, and the constant pressure outer cylinder 2 is sleeved outside the constant pressure inner cylinder 3 and the floating piston 4, and the constant pressure outer cylinder 2 and the constant A chamber is formed between the inner cylinders 3, one end of the floating piston 4 is fixedly connected with the floating shaft 1, and the other end is located in the chamber and divides the chamber into the first chamber 5 and the second chamber 6, the constant pressure outer cylinder The side wall of the body 2 is provided with a first air inlet 7 and a second air inlet 8, the first air inlet 7 is in communication with the first chamber 5, and the second air inlet 8 is connected to the second chamber 6. through.
本发明处于工作状态时，通过第一进气口7或者第二进气口8向第一腔室5或者第二腔室6内充气。当通过第一进气口7向第一腔室5内充气时，浮动活塞4受气流作用向第二腔室6方向移动，由于浮动活塞4与浮动轴1固定连接，因此浮动活塞4带动浮动轴1一起运动，浮动轴1处于伸出的状态。当第一腔室5输入的气流一定时，浮动活塞4受力一定，因此通过浮动活塞4传递给浮动轴1的力是恒定的，即所说的轴向恒力浮动。当通过第二进气口8向第二腔室6内充气时，浮动活塞4受气流作用向第一腔室5方向移动，浮动活塞4带动浮动轴1一起运动，浮动轴1处于缩入的状态。当第二腔室6输入的气流一定时，浮动活塞4受力一定，因此通过浮动活塞4传递给浮动轴1的力也是恒定的。值得注意的是，由于浮动活塞4可在恒压外缸体2和恒压内缸体3形成的腔室内活动，因此第一腔室5和第二腔室6的界线并没有明显的界定。另外，还值得注意的是，浮动活塞4与恒压外缸体2并不一定是完全绝密的，因此当第一进气口7向第一腔室5内充气时，气体也可通过浮动活塞4与恒压外缸体2之间的缝隙以及第二进气口8排出；当第二进气口8向第二腔室6内充气时， 气体也可通过浮动活塞4与恒压外缸体2之间的缝隙以及第一进气口7排出。通过上述的设置，可实现在轴向恒力浮动，这个恒力，可以是工作时对工件恒定下压的力，也可以是对工件恒定上拉的力，不管是哪种恒力，都能实现对加工器件的轴向恒力作用，从而起到恒力作用、保护器件、提高精度的目的。When the invention is in operation, it is inflated into the first chamber 5 or the second chamber 6 through the first intake port 7 or the second intake port 8. When inflating into the first chamber 5 through the first air inlet 7, the floating piston 4 is moved toward the second chamber 6 by the air flow. Since the floating piston 4 is fixedly connected with the floating shaft 1, the floating piston 4 drives the floating The shaft 1 moves together and the floating shaft 1 is in an extended state. When the airflow input from the first chamber 5 is constant, the floating piston 4 is forced to be constant, and therefore the force transmitted to the floating shaft 1 through the floating piston 4 is constant, that is, the axial constant force floats. When the second air inlet 8 is inflated into the second chamber 6, the floating piston 4 is moved toward the first chamber 5 by the air flow, and the floating piston 4 drives the floating shaft 1 to move together, and the floating shaft 1 is retracted. status. When the airflow input from the second chamber 6 is constant, the floating piston 4 is forced to be constant, and therefore the force transmitted to the floating shaft 1 through the floating piston 4 is also constant. It is to be noted that since the floating piston 4 is movable in the chamber formed by the constant pressure outer cylinder 2 and the constant pressure inner cylinder 3, the boundary between the first chamber 5 and the second chamber 6 is not clearly defined. In addition, it is also worth noting that the floating piston 4 and the constant pressure outer cylinder 2 are not necessarily completely dense, so that when the first intake port 7 is inflated into the first chamber 5, the gas can also pass through the floating piston. 4 and the gap between the constant pressure outer cylinder 2 and the second air inlet 8; when the second air inlet 8 is inflated into the second chamber 6, the gas can also pass through the floating piston 4 and the constant pressure outer cylinder The gap between the bodies 2 and the first air inlet 7 are discharged. Through the above arrangement, it is possible to achieve constant force floating in the axial direction. This constant force can be a force that constantly presses the workpiece during operation, or a force that constantly pulls up the workpiece, regardless of the constant force.
